Abstract

以环形太阳望远镜为应用背景,研制了一种基于步进电机的位移促动器,并进行了性能实验测试,获得了该位移促动器的性能指标。分析了常见的大行程高精度位移促动器的结构形式,选择位移缩放式作为位移促动器的基本结构。该位移促动器采用步进电机集成行星减速器作为驱动元件,以具有特殊消间隙结构的螺旋传动作为位移缩放机构,为实现高分辨率、高刚度和高精度的位移促动器的设计。开展了位移促动器的性能实验测试,结果表明:该位移促动器轴向位移量程为±2mm,不同负载下均能实现1μm步长分辨率,位移闭环输出精度优于1μm。研制的位移促动器为环形太阳望远镜的建设提供重要的技术支持,并可为其它精密光学镜面支撑系统的工程应用提供参考。 

Other Abstract

A displacement actuator using a stepper motor was developed for a ring solar telescope, and comprehensive tests were performed to evaluate of its performance. Three design schemes were commonly used in the development of large-stroke and high-precision displacement actuators. And we chose the Displacement Scaling as the basic structure of Displacement Actuator.To achieve high resolution, high stiffness and high precision, Displacement Actuator was driven by Stepper Motors and Planetary Reducers, and eliminated the interval by screw rotation. The experiments of performance test results indicated that the Displacement Actuator’s axial displacement range is ±2mm,1μm step resolution can be achieved under different workloads, and step resolution can be achieved under different workloads, and the output accuracy of the position closed-loop is better than 1μm. The Displacement Actuator we developed provided important technical support for the ring solar telescope,as well as references for the engineering application of other precision optical mirror support system.
